Definitions
- the present invention relates to a device for measuring a vehicle on a road.
- Measuring vehicles is particularly useful for determining the suitability of using a road section, e.g. a tunnel or a toll road, or a place, e.g. of a tolled parking lot or local area, of great importance.
- a road section e.g. a tunnel or a toll road
- place e.g. of a tolled parking lot or local area
- user charges should be determined as a function of vehicle height and / or width.
- the measurement of a vehicle should take place as possible without disturbing the flow traffic, ie while driving on the road. For this purpose, for example, measuring gantries running across the roadway are erected and equipped with sensors for vehicle surveying.
- a vehicle height can be determined by means of light barriers transversely radiating at different heights.
- an image can first be taken of a vehicle and the vehicle can then be measured by means of optical image evaluation.
- a laser scanner mounted on a measuring portal is known, which can project two differently inclined scanning compartments onto the roadway or vehicle surface by means of a rotating deflecting mirror with differently inclined mirror surfaces. Due to the fanning out of the laser measuring beams, shading effects occur, so that the side faces of a vehicle facing away from the scanner can not be detected and therefore can not be measured.
- the invention has for its object to provide a device for measuring a vehicle, which overcomes the disadvantages of the prior art and is flexible to use.
- a device for measuring a vehicle with a support structure having a transversely orientable support axle, a plurality of transmitting elements, which are mounted distributed on the support structure along the support shaft and each emit a light measuring beam in a direction perpendicular to the support axis extending beam down, at least one receiving element mounted on the support structure, which receives reflected light measuring beams, and an evaluation unit connected to the transmitting and receiving elements for measuring the time of light and, therefrom, measuring a vehicle, which device is characterized in that the emission directions of at least two transmitting elements are non-parallel to each other.
- the light measuring beams together form a two-dimensional measuring area on the road surface and are nevertheless always aligned in directions parallel to the travel direction, so that they can measure a vehicle in three dimensions without lateral shadowing effects.
- the beam distances transversely to the direction of travel can be chosen independently of each other in different directions of radiation, which can be saved as needed transmitting and / or receiving elements and thus also computing power in the evaluation.
- the support structure is relieved, so also a one-sided support of the consequently slim, projecting over the roadway part of the support structure is possible. So it can be performed, for example, for maintenance, also pivotable.
- transmitter elements with mutually parallel emission directions form a group and the device has at least two groups.
- groups of parallel light measuring beams together form scan lines running across the roadway and can be evaluated jointly or with regard to a specific task.
- additional components e.g. Traffic cameras, controlled or the light measuring beams of a second group are influenced in their temporal sequence.
- Energy and / or computing power can be saved in low-traffic times.
- the transmitting elements of a first group have regular first mutual distances and the transmitting elements of a second group thereof have different regular second mutual distances.
- the mutual distances of the light measuring beams are adapted to different tasks that require different resolutions; their regularity simplifies the alignment of the measuring device and the evaluation.
- a preferred embodiment of the invention is characterized by a first group of closely spaced transmitting elements with vertical emission directions, at least a second group of widely spaced transmitting elements with emission directions at a first angle to the vertical, and at least a third group of closely spaced transmitting elements having radiating directions at a second angle to the vertical.
- Each group of transmitting elements can serve a specific purpose: the evaluation device is particularly preferably designed to evaluate the reflections of the light measuring beams of the first group for vehicle classification, those of the second group for vehicle tracking and those of the third group for vehicle detection.
- an image of the vehicle registration can be triggered, whereupon the vehicle with light measuring beams of the second group - in lower resolution over a long distance - can be traced without gaps up to light measuring beams of the first group, which set close and provide particularly good receivable reflections with a vertical beam direction, so that the vehicle classification can be carried out with high precision. Thanks to the complete tracking of the vehicle through the entire two-dimensional measuring range, the combination of vehicle registration number and measurement or classification result is fail-safe.
- the vehicle can be tracked with the aid of subordinate second groups up to a (new) detection and a (further) third group and, if desired, a (further) image acquisition be triggered For example, for front and rear photos of the same vehicle and its number plate.
- each transmitting element on the carrier structure is assigned its own receiving element in the immediate vicinity. This allows a simplified assignment in the evaluation of the individual reflected light measuring beams and also simplifies the alignment of the transmitting and receiving elements. Furthermore, it is facilitated that several or all transmitting elements simultaneously emit light measuring beams, which are received by the respective associated receiving elements and evaluated with the aid of the evaluation device with respect to the light transit time.
- each receiving element In order to reduce the disturbing influence of scattered light, it is preferable for each receiving element to be a visual field stop upstream. In addition to a reduction in the susceptibility to environmental influences, reflections of the light measuring beams of adjacent transmitting elements are also masked out, which allows the simultaneous operation of several or all transmitting elements.
- each transmitting element is formed by the mouth of a light-conducting fiber, which is fed by a light source.
- the light weight of the fibers provides a particularly slim and lightweight support structure, which facilitates rapid assembly and maintenance and reduces the visual impact on the environment.
- the light-conducting fibers emanate from a central location in the device, to which one or more light-conducting fibers each have a light source. This can save light sources and the remaining (s), if necessary, centrally maintained. The simultaneous operation of several or even all transmitting elements is ensured at the same time. Also, the photoconductive fibers can be led out of the support structure and e.g. be outsourced to an associated control box of the device, making them even more easily accessible.
- each receiving element is formed by the junction of a light-conducting fiber, which is fed to an opto-electrical converter. Similar to the aforementioned variant, this reduces the weight along the axle. At the same time, such an embodiment enables the central evaluation of the reflected light measuring beams directly on the basis of the optical signals.
- the opto-electrical converter is particularly preferably an image sensor, to the pixels of which one of the light-conducting fibers is guided in each case.
- an image sensor suitable for the time of flight measurement can also accurately record and allocate simultaneously emitted light measuring beams or their reflections with regard to their transit time and thereby determine individual distances.
- the image sensor can again sit in a central location, eg in the control box on the support structure.
- the transmitting elements are light-emitting diodes (LEDs) or laser diodes
- the receiving elements are opto-electrical transducers which are exposed on the carrier structure to the outside.
- LEDs light-emitting diodes
- the receiving elements are opto-electrical transducers which are exposed on the carrier structure to the outside.
- a mixed embodiment e.g. with decentralized light or laser diodes as transmitting elements and junctions of light-conducting fibers as receiving elements with central image sensor, or conversely with central light emitting or laser diodes and outlets of light-conducting fibers as transmitting elements and decentralized opto-electrical transducers, e.g. Photodiodes would be equally possible. Due to the small size of today's light, laser and photodiodes while a slim support structure is maintained.
- the support structure can be particularly advantageously constructed as a standardized module, which is equipped as desired with transmit and receive elements by the support structure has a plurality of prepared recordings for each transmitting and / or receiving element, which recordings grid-like over a downward side of the Carrier structure are distributed.
- a plurality of prepared recordings for each transmitting and / or receiving element which recordings grid-like over a downward side of the Carrier structure are distributed.
- different mutual spacings of the transmitting and / or receiving elements and thus adaptation to different environmental conditions and tasks can be achieved in a simple manner in different emission directions.
- the individual recordings can already be prepared for predetermined emission directions and / or assign a prepared field of view to the receiving elements.
- the receptacles are clip holders for the insertion of light emitting diodes, laser diodes and / or optoelectric transducers. This allows for rapid assembly or disassembly of said components at furthermore any equipment.
- the possible low wall thickness of the support structure reduces their weight.
- the receptacles are preferably a wall of the support structure passing through shafts for the passage of photoconductive fibers.
- Such shafts can also be very narrow in view of the small fiber diameter and thereby favor the rapid onset of the fibers.
- the outer sections of the receptacles are designed as visual field diaphragms. This may be a region of smaller diameter of said shafts or a formed on the clip holders part of the images, which eliminates separate components.
- a vehicle 1 is measured while driving on a roadway 2 by means of a device 3 at least in relation to its width and height.

- the close distance a 1 leads to a high resolution in this measurement or classification.
- the vehicle 1 is detected while passing through the measuring area 21 by the light measuring beams 12 of the second groups 19, 19'("trackinggroups").
- this serves to track the vehicle 1 in the entire measuring area 21 without gaps, and thus unambiguously associates, for example, an image acquisition of the camera units 22, 22 'triggered by the third groups 20, 20' with a vehicle 1 measured and classified using the first group 18 to be able to.
- the transmitting elements 11 of the second groups 19, 19 ' are widely spaced from one another (a 2 > a 1 , a 2 > a 3 ).
- the distances a 1 , a 2 , a 3 of the transmitting elements 11 of the various groups 18, 19, 19 ', 20, 20' can be chosen differently than in the illustrated example. Also, other groups or other suitable, even irregular pattern 17 can be broadcast.
- the light measuring beams 12 may be in the visible wavelength range, but are invisible in the present example to avoid interference with traffic.
- the measurement of the length of the vehicle 1 or the scaling of its scanning point cloud can be achieved, for example, by linking the evaluations of a plurality of receiving elements 14 of different groups 18, 19, 19 ', 20, 20' or by means of an additional speed measurement of the vehicle 1.
- Such a speed measurement can be done via separate speed sensors (not shown), or by means of Doppler measurement using the emitting at an angle ⁇ 1 , ⁇ 2 relative to the vertical transmitting elements 11, or based on the time span between the detection of a vehicle 1 using one of Groups 18, 19, 19 ', 20, 20' and the recognition by means of a downstream group.
